XML over HTTP

This question is kind of to Sean Hinde in reference to this past message:
http://www.erlang.org/ml-archive/erlang-questions/200101/msg00050.html
where Sean said, among other things,
"XML over HTTP - this is what we chose. The Java side sends Erlang a HTTP
POST containing some XML with the data. Erlang responds with an XML result."
QUESTION: Is there any code publicly available that demonstrates this?
thank you to anyone with information,
